We decided to engage a knowledgeable guide for this important historical site. Mario has 42 years' experience and was very accommodating. And was good with the 4 kids, aged 7 - 9, who were a bit antsy, but Mario tried to keep them engaged, teasing them, and doing math problems having to do with the number of steps/ancient calendars. He dropped us off at a restaurant, when we asked. And he even got the kids pyramid souvenirs! We recommend Mario for his knowledge, patience, & accommodating our requests.
TOUR GUIDE RESPONSE: You are very kind with me. Thank you!
